HIGH-VISCOSITY XANTHAN POLYMER PREPARATION

Japanese Patent JP2011067205

A

To provide xanthan with higher specific viscosity characteristics, wherein increasing the molecular length of xanthan polymer makes a higher viscosity xanthan composition.

A high-vixcosity xanthan polymer preparation is obtained by selectively increasing, in a Xanthomonas campestris culture, the amount of gene products of gumB and gumC but not of orfX nor of a gene selected from the group consisting of gumD-gumG. The increasing method includes introducing one or more additional copies of gumB and gumC.
